Haematopoietic stem/progenitor cells

Abstract

The invention relates to an isolated cell having, after culturing a pluripotent stem cell (PSC) in a medium comprising a WNT agonist and an ACTIVIN antagonist, increased HOXA gene expression relative to a PSC not cultured in a medium comprising a WNT agonist and an ACTIVIN antagonist, wherein the cell with increased HOXA gene expression is capable of generating a definitive haematopoietic stem/precursor cell. The invention also relates to use of the cell for generating a definitive haematopoietic stem/precursor cell, and a method for differentiating a PSC into a definitive haematopoietic stem/precursor cell and a definitive haematopoietic stem/progenitor cell differentiated from a PSC by the method. The invention further relates to a therapeutic composition comprising a cell of the invention, and to therapeutic methods and uses of a cell of the invention. The invention also relates to a reporter cell comprising distinguishable SOX17 and RUNXIC reporters, for use in tracking the differentiation of a PSC into a definitive haematopoietic stem/progenitor cell.
